The process of aging is a phenomenon that occurs universally in all living organisms. It begins during intrauterine life and persists until death. Obsessive-compulsive disorder (OCD) can significantly impact the lives of older adults, especially in their relationships with others, including spouses or partners. These relationships often involve conflicts or may be affected by the individual's OCD symptoms, such as rituals. Hence, the present study aimed to investigate the prevalence of OCD among the older person population.
The systematic review and meta-analysis were carried out without a time limit until March 2024. To identify articles pertinent to the study's objectives, searches were conducted on Embase, PubMed, Scopus, WOS, and Google Scholar databases using appropriate keywords and validated with MeSH/Emtree. The I index was utilized to assess heterogeneity among the studies.
Ultimately, 10 articles meeting all the inclusion criteria had a sample size of 54,377. The estimated prevalence of OCD in the older person worldwide is 2.4% (95% confidence interval: 1.8%-3.3). The Asian continent showed the highest prevalence of OCD in the older person at 3.5% (95% confidence interval: 2.4-5.1), while the female population had an estimated prevalence of 2.7% (95% confidence interval: 1.9-3.8). As the publication year increased, there was an upward trend in the quality assessment score and the age of OCD prevalence in the older person (P < 0.05).
The results of the present study indicate a high prevalence of OCD among the older person. Hence, it is advised that greater attention be directed towards this issue by experts, authorities, and health policymakers.
衰老过程是所有生物体普遍存在的现象。它始于宫内生活，持续到死亡。强迫症（OCD）会对老年人的生活产生重大影响，尤其是在他们与他人的关系中，包括配偶或伴侣。这些关系通常涉及冲突，或者可能受到个体 OCD 症状的影响，例如仪式。因此，本研究旨在调查老年人中 OCD 的患病率。
系统回顾和荟萃分析没有时间限制，直到 2024 年 3 月。为了确定与研究目标相关的文章，在 Embase、PubMed、Scopus、WOS 和 Google Scholar 数据库中使用适当的关键词进行了搜索，并使用 MeSH/Emtree 进行了验证。I 指数用于评估研究之间的异质性。
最终，有 10 篇符合所有纳入标准的文章，样本量为 54377 人。全球范围内老年人 OCD 的估计患病率为 2.4%（95%置信区间：1.8%-3.3%）。亚洲大陆老年人 OCD 的患病率最高，为 3.5%（95%置信区间：2.4-5.1%），而女性人群的估计患病率为 2.7%（95%置信区间：1.9-3.8%）。随着发表年份的增加，质量评估评分和老年人 OCD 患病率呈上升趋势（P<0.05）。
本研究结果表明老年人 OCD 的患病率较高。因此，建议专家、当局和卫生政策制定者更加关注这一问题。
